To all whom it may concern.- y

Be it known that I, ALBERT IIUNTL'ISIY, a citizen of the United States, residing at Ostrander, in the county of Delaware and State of Ohio, have invented a new and useful Improvement in SeedDrills, of which the following is a specification.

My invention relates to an improvement in seeddrills adapted particularly for drilling seed between rows of standing corn; and it consists in the peculiar construction and combination of devices, that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a seed-drill embodying my improvements. Fig. 2 is a top plan view of the same. Fig. 3 is a vertical longitudinal sectional view taken on the line m x of Fig. 2. Fig. 4 is a vertical transverse sectional view taken on the line y y of Fig. 1.

A represents a U-shaped bar, the front portion of which forms a semicircular guidingyoke, B, and the rearwardextending arms of which form side beams,0. Said beams are connected near their front and rear ends by crossoars D E, the ends of which project slightly beyond the outer sides of beams C.

F represents a pair of longitudinal metallic bars or plates, which are arranged parallel with each other and connect the cross-bars D E at suitable distances from the centers of the same.

G represents an arched axle, which has a central portion arranged transversely over the plates F, at the centers of the same, and bolted thereto, as shown. The depending vertical arms of the arched axle are provided at their lower ends with outwardly-projecting spindles H, on which are journaled wheels I K, of suitable size and diameter. Secured to the hub of the wheel I, on the inner side of the same, is a pulley, L.

M represents a plate, which connects the central portion of the curved yoke B and the front crossbar, D. From the upper side of this plate projects a series of ears, N, in which is guided a longitudinally-movable springactuated bolt, O, the front end of which is T- shaped, has a central notch, P, and has its ends beveled rearward in opposite directions from the said notch. Y

S represents a pair of shafts or thills,which are made from a single piece of material, bent and fashioned int-o the shape of the letter U, and provided with a cross-bar, T. The center of the yoke or bow U at the rear end of the thills is pivoted on the center of the front cross-bar, D, by means of a vertical bolt, V, and the upper end of the latter is connected to the central upper portion of the arched axle by means of a hammer-strap, W.

From the foregoing description it will be understood that the thills are pivotally connected to the frame of the drill, so that the thills may be swung to either side ofthe frame when the machine is being turned at the end of the furrow, thereby enabling the drill to be turned in a very small space, and consequently preventing the horse from tramping down the growing cornstalks at the ends of the rows.

The cross-bar T of the thills is provided at its center, on its rear side, with a plate, X, from which depends a stud, Y, that is adapted to be engaged by the notch P ofthe bolt O, so as to lock the thills rigidly to the frame,when the same are in line therewith. On the crossbar T is also pivoted the usual whifiletree, Z. The upper side of the curved yoke B is provided with a sheathing-plate, A, of suitable metal, adapted to prevent wear. The outer edge of this sheathing-plate, which is semi circular and conforms to the shape of the bow or yoke, projects beyond the outer side of the latter, and thereby forms a guiding-flange, which is engaged by a lip, B', that is formed on the front side of a plate, C', which is secured under the center of a crossbar, T. By this means the connection between the thills and the machine-frame is strengthened and the pivotal bolt V is relieved of strain. Suitable wear-plates, D', are also secured to the opposing central portions of the bow U of the thills and the cross-bar D of the frame.

E represents a pair of fenderstraps, which are securedv to the projecting ends of the crossbars E D, and have their front ends secured to the sides of the front bow or yoke of said frame, the function of these fender-straps be- IOO ing to part the cornstalks on opposite sides of the path of the machine, and thereby enable the drill to be drawn between the rows of growing corn without injuring the same.

F represents a hopper, which is arranged transversely over the frame, near the rear end thereof, and is provided at its ends with depending supporting knees or standards G', which are secured to the side beams of the frame. In the bottom of the said hopper are a number of discharge-openings, H',which are arranged at suitable distances apart. From the under side of the hopper depend a number of vertical feed-cases, l', which have their rear sides open and have their lower and front sides curved, as shown. Journaled in the said cases,and arranged underthe hopper, is a transverse shaft, K', to which is keyed a number of feed seed-wheels, L', that are arranged in the cases l', and are under the discharge-openings in the bottom of the hopper.

M' represents a pulley, which is also keyed .to the shaft K', and is also connected -to the pulley L by means of an endless belt, N.

O' represents a plate, which is arranged transversely on the rear side of the frame, and is provided with a number of openings,which are below the rear open ends of the cases I', and in the said openings are secured the upper ends of a number of depending spouts, P.

R' represents a series of iiexible seed-tubes, which have their upper ends attached to the spouts P', and depending therefrom.

S' represents a rod, which is supported in suitable keepers that depend from the front cross-bar, D. To the said rod are pivoted the front ends of a series of rearward-extending link-arms/,lC Said link-arms have their front and rear ends bifurcated, as shown.

U' represents a series of drill-holes, each of which is provided at its upper end with a clamping-collar, V', that has a forward-extending arm, W', which is pivoted in the bifurcated rear end of one of thelink-arms. Each of the said arms W' has a transverse opening in its upper corner, in which is inserted a frangible pin, X', the function of the said pins being to normally keep the hoes at work, but said pins being adapted to break should the hoes encounter obstructions, so that the said hoes mayturn rearward on their pivotal connections with the link-arms, and thereby avoid being injured.

r[he flexible seed-tubes extend downward in the drill-hoes in the usual manner, as shown.

Y' represents a rocking beam, which is provided with trunnions at its ends on its inner corners, which are journaled in suitable bearn ings on the rear end of the frame. The `said beam is provided on its upper side with a series of keepers, Z', to which are attached the upper ends of chains A?, the lower ends of which are connected to the clampingfcollars at the upper ends of the drillhoes.

B2 represents an arm which projects outward from the rocking beam and serves as a lever by which the latter may be turned, so as to raise or lower the drill-hoes; as will be readily understood. A hook, C2, is pivoted :inasuitable support that projects from the rear side of the hopper, and said hook is adapted to engage the arm Bz when the latter is raised, so as to support the drill-hoes in their elevated position.

DZ represents a hail, which is bent substantially in the form of the letter U, and has the front end of its arms pivoted on the outer sides of the beams C, near the rear ends thereof, the function of the said bail being to serve as a handle, whereby the operator walking in rear of the machine may raise the same, so as to enable it to pass over obstructions, and may guide the machine out of the way of stalks of standing corn. The extremities of the arms of the bail DAl bear against the projecting ends of the cross-bar E, so that by depressing the rear end or cross-bar of the bail the front ends of its arms will be raised and the machine lifted off the ground.

It will be understood from the foregoing description that a machine thus constructed is adapted to be drawn by one horse and to drill wheat, rye, or other cereals between rows of standing corn before the corn crop has been gathered.

Having thus described my invention, I claiml. The combination, in a seed-drill, of the frame having the curved bow or yokeB at its front end and the transverse bar D, the shafts or tliills having the curved bow or yoke U at their rear ends pivoted to the center of the bar D, the crossAbar of said shafts or thills bearing on the curved yoke or bow at the frontend of the frame,a wear'ingplate secured on the upper side of the bow B and having its edge projecting forward of the same, and the plate C', secured to the cross-bar of the thills and having the lip B engaging the edge of the wearplate, substantially as described.
